When EmptyCriterionValid property is true, this method is expected to
return a query which does not match any document. This only happens when
query_list is empty, but because of category membership checking,
query_list is never empty: it at least contains two ComplexQueries which
themselves may contain an empty query list, and which match all documents.
Calling getCategoryParameterDict with an empty list is dubious, but
changing its behaviour in ZSQLCatalog may affect more than just predicates,
so change the behaviour in Predicate class directly by checking whether
there is any category being matched to begin with.

Pygolang installs import hooks for pytest and ipython, to add
exception-chaining support into them(*) _iff_ (if and only if) those
modules are actually used. This works via Importing[1] which
pre-installs artificial modules into sys.modules that catch
__getattribute__ and try to import corresponding module for real on
first access. Usually everything is fine.

But with pylint/astroid, if the checker code happens to run with those
LazyModules installed, and the checked code has `import sys` somewhere,
astroid eventually delves into processing sys, then sys.modules and
wants to represent that sys.modules dict as dict of constant. Then, when
e.g. sys.modules['_pytest'] is processed, corresponding module object is
checked for .__class__, which raises ImportError if pytest is not
actually available:

    ( https://erp5js.nexedi.net/#/test_result_module/20220127-129289AE2/33 )
    ...
    File ".../eggs/astroid-1.3.8-py2.7.egg/astroid/node_classes.py", line 553, in __init__
        for k, v in items.items()]
      File ".../eggs/astroid-1.3.8-py2.7.egg/astroid/node_classes.py", line 962, in const_factory
        return CONST_CLS[value.__class__](value)
      File ".../eggs/Importing-1.10-py2.7.egg/peak/util/imports.py", line 254, in __getattribute__
        _loadModule(self)
      File ".../eggs/Importing-1.10-py2.7.egg/peak/util/imports.py", line 222, in _loadModule
        reload(module)
    ImportError: No module named _pytest

-> Fix it by detecting those lazy modules and not letting them go through
normal const_factory not to crash.

erp5_base: add constraint and action to make sure Employee Number is unique instead of manually setting

We make it possible to define function the same way it's currently
possible to define accounts. The idea is similar: to be able to use this
information in accounting generation rules.

The typical accounting generation configuration using this will use the
function defined on the supply line if any is defined and with a fallback
to the function defined on business process' trade model path.

For now we don't introduce such configuration by default, but this may
become part of  the configuration generated by configurator some day.

The view of accounting transactions have dynamic columns so that all the
information that matters the most is displayed directly on the "main"
view. This extends the columns to add a column for all the items attached
to accounting movements.

Without these accessors, we have to use constructs like:

    resource.edit(
        default_purchase_supply_line_destination_account='account_module/123'
    )

with the accessors, we can use:

    resource.edit(
        default_purchase_supply_line_destination_account_value=account,
    )

The former is a bit error prone, because typos in the property name
silently create a local propery and typos in the relative URL make a
"broken" relation.
